All compounds within the purview of the above generic formulae exhibit miticidal, mite ovicidal and herbicidal activity to a lesser or greater extent. Some of these compounds exhibit very powerful miticidal, mite ovicidal or herbicidal activity in extremely small dosages while others require larger dosages to be pesticidally effective. In general, the compounds of this invention that exhibit the highest order of herbicidal activity also exhibit the highest order of miticidal and mite ovicidal activity. Miticidal and/or mite ovicidal and herbicidal activity is greatest in those compounds having a hydrogen, methyl, nitro, or halogen substituent at one of the ortho positions of the 2-phenyl moiety, and a methyl or halogen group at the other position. Herbicidal activity is greatest in those compounds having, in addition to the aforementioned, ethyl and CF₃ at the ortho position of the 2-phenyl moiety.

It has also been found that some of the pesticidal compositions of this invention exhibit excellent fumigant properties. In addition, these compounds are relatively non-toxic to mammals when used in amounts sufficient to kill mites, mite eggs or undesirable plant growth.

R₁, R₂, R₄ and R₅ are individually hydrogen, methyl, halo or nitro with the proviso that when R₁ is hydrogen or nitro, then R₅ cannot be hydrogen or nitro;

R₃ is hydrogen, methyl or halo;

R₆ through R₁₁ inclusive are individually hydrogen, C₁ -C₈ alkyl, CF₃, unsubstituted phenyl, or

R₈ and R₉ together form a cyclopentyl or cyclohexyl ring.

Preferred because of their higher level of herbicidal activity are the 2-aryl-1,3-cyclohexanedione enol ester compounds of this invention in which:

R₁ is ethyl;

R₂ to R₅ inclusive are individually hydrogen, methyl, CF₃ or halogen

with the proviso that halogen atoms may not occupy adjacent positions on the aromatic ring;

R₆, R₇, R₁₀ and R₁₁ are hydrogen;

R₈ and R₉ are individually hydrogen, unbranched C₁ -C₄ alkyl, isopropyl, tertiary butyl, diethyl methyl, cycloalkyl, CF₃

with the proviso that when R₈ or R₉ is ethyl, isopropyl, or diethyl methyl, then R₁₄ is C₁ to C₄ alkyl and R is C₁ C₁₅ alkyl; or

R₁₃ and R₁₄ are individually C₁ to C₃ alkyl.

The 2-aryl-1,3-cyclohexandione enol ester compounds of this invention can be conveniently prepared by a variety of methods. Two preferred methods which utilize the 2-aryl-1,3-cyclohexanedione parent compound as the precursor are illustrated by the general reaction schemes set forth below in which R, R₁, R₂, R₃, R₄, R₅, R₆, R₇, R₈, R₉, R₁₀ and R₁₁ are as described above and X is halogen, or ##STR5## except as noted: ##STR6##

In the reactions illustrated in METHOD I one equivalent of the corresponding 2-aryl-cyclohexane-1,3-dione compound is reacted with an appropriately substituted acid halide or anhydride compound in the presence of at least one equivalent of an acid acceptor, preferably in an inert solvent.

The acid acceptor utilized in the reactions of METHOD I can be either an organic or an inorganic base. Illustrative of organic bases that are useful as acid acceptors in the conduct of these reactions one can mention tertiary amines, such as triethylamine, pyridine, trimethylamine or 1,4-diazobicyclo[2.2.2] octane; or alkali metal alkoxides, as for example, sodium methoxide, sodium ethoxide or the like. Bases such as sodium carbonate, sodium hydroxide or potassium hydroxide are illustrative of inorganic bases that are useful as acid acceptors. Preferred organic acid acceptors are tertiary amines such as triethylamine, pyridine or trimethylamine.

In general, any organic solvent that is inert to the reactants or reaction conditions may be employed in the reaction of METHODS I. Illustrative of organic solvents which are generally suitable for use in the conduct of these reactions are saturated, unsaturated and aromatic hydrocarbons, e.g., hexane, cyclohexane, octane, cyclohexene, dodecane, naphtha, Decalin, kerosene, cycloheptane, benzene, toluene, xylene, naphthalene or the like; ethers such as dioxane, tetrahydrofuran, diethyl ether; tetrahydropyran, 1,2-dimethyoxybenzene, 1,2-diethyl benzene, the dialkyl ethers of ethylene glycol, of propylene glycol or chlorinated aliphatic hydrocarbons as for example, chloroform, dichloromethane, methylene dichloride, 1,1-dichloroethane, carbon tetrachloride or the like.

In a preferred embodiment, the reactions, illustrated in METHOD I are conducted in a solvent that also functions as the acid acceptor. Illustrative of such multifunctional solvents are N,N-dimethylaniline, pyridine, alpha-picoline, any lutidine, collodine or any like aromatic or heterocyclic tertiary amine compound.

The reactions illustrated in METHOD I are neither temperature nor pressure sensitive and can be conducted over a broad temperature and pressure range to yield the desired product. Preferably, these reactions are conducted at a temperature of from -40° C. to about 120° C. and at atmospheric or autogeneous pressure.

The acid halide, acid and anhydride compounds utilized as reactants in the procedure described in METHODS I above are known classes of compounds that can either be obtained from commercial sources or prepared in accordance with conventional methods known to those skilled in the art.

The 2-aryl-1,3-cyclohexanedione compounds utilized as reactants in the procedure of METHOD I can be conveniently prepared in accordance with a number of synthetic procedures. For example, 2-aryl-1,3-cyclohexanedione compounds in which R₅ is hydrogen can be prepared by heating the corresponding 6-aryl-5ketopolyalkyl hexanoic acid compound with sulfuric acid or alternatively by treating the corresponding 6-aryl-5-ketopolyalkylhexanoic acid ester with base. The 2-aryl-cyclohexane-1,3-dione compounds in which at least one ortho substituent is alkyl and the other ortho substituent is other than hydrogen, can be conveniently prepared by the benzophenone sensitized photolysis of the corresponding 2-diazocyclohexane-1,3-dione compound in an appropriately substituted aromatic solvent. The remaining 2-aryl-1,3-cyclohexanedione precursors can be conveniently prepared by reacting the corresponding 1,3-cyclohexanedione compound with an appropriately substituted halonitrobenzene compound. These synthetic procedures are described in more detail in U.S. Pat. No. 4,209,532 entitled "BIOCIDAL 2ARYL-1,3-CYCLOHEXANE-DIONE COMPOUNDS".

This solid was chromatographed through 250 g of silica gel (0.063-0.2 mm) eluting with a gradient from pure benzene to 80:20 benzene-ethyl acetate. A total of 2.60 g (31%) of a white solid (honogeneous by thin layer chromatography) was obtained and recrystallized from diisipropyl ether to give 1.96 g of 2-(2',4',6'-trimethylphenyl)-1,3-cyclohexanedione as white crystals, mp 196°-198° C.

Calculated for: C₁₅ H₁₈ O₂ : C, 78.23; H, 4.88. Found: C, 77.94; H, 8.20.

Selected 2-aryl-1,3-cyclohexanedione enol ester compounds representative of those useful in accordance with this invention were tested with respect to their miticidal, mite ovidical and pre-emergent and post-emergent herbicidal activity.

Suspensions of the test compounds were prepared by dissolving one gram of compound in 50 milliliters of acetone in which had been dissolved 0.1 gram (10 percent of the weight of compound) of an alkyl-phenoxyethanol surfactant, as an emulsifying or dispersing agent. The resulting solution was mixed into 160 milliliters of water to give roughly 200 milliliters of a suspension containing the compound in finely divided form. The thus prepared stock suspension contained 0.5 percent by weight of compound. The test concentrations employed in the tests described hereinbelow were obtained by diluting the stock suspension with water. The test procedures were as follows:

MITE FOLIAGE SPRAY TEST

Adults and nymphal stages of the two-spotted mite (tetranychus uriticae (Koch)), reared on Tendergreen bean plants at 80±5° F., and 50±5° percent relative humidity, were the test organisms. Infested leaves from a stock culture were placed on the primary leaves of two bean plants six to eight inches in height, growing in a two-and-a-half inch clay pot. 150-200 Mites, a sufficient number for testing, transferred from the excised leaves to the fresh plants in a period of twenty-four hours. Following the twenty-four hour transfer period, the excised leaves were removed from the infested plants. The test compounds were formulated by diluting the stock suspension with water to provide suspensions containing 500 parts of test compound per million parts of final formulation. The potted plants (one pot per compound) were placed on a revolving turntable and sprayed with 100-110 milliliters of test compound formulation by use of a DeVilbis spray gun set at 40 psi. air pressure. This application, which lasted 30 seconds, was sufficient to wet the plants to run-off. As a control, 100-110 milliliters of a water solution containing acetone and emulsifier in the same concentrations as the test compound formulation, but containing no test compound, were also sprayed on infested plants. The sprayed plants were held at 80±5° F. and 50±5 percent relative humidity for four days, after which, a mortality count of motile forms was made. Microscopic examination for motile forms was made on the leaves of the test plants. Any individual which was capable of locomotion upon prodding was considered living.

MITE OVICIDE TEST

The test organism was the egg of the two-spotted mite (Tetranychus uriticae (Koch)), as obtained from adults reared on Tendergreen bean plants under controlled conditions of 80±5° F. and 50±5 percent relative humidity. Heavily infested leaves from a stock culture were placed on the primary leaves of two bean plants six to eight inches in height, growing in a two-and-a-half inch clay pot. Females were allowed to oviposit for a period of 48 hours and then the leaves of the infested plants were dipped in a solution containing 800 parts of tetraethyl pyrophosphate per million parts of water in order to destroy the reproductory forms and thus prevent further egg laying. This solution of tetraethyl pyrophosphate does not affect the viability of the eggs. The plants were allowed to dry thoroughly. The test compounds were formulated by diluting the stock suspension with water to give a suspension containing 500 parts of test compound per million parts of final formulation. The potted plants (one pot per compound) were placed on a revolving turntable and sprayed with 100-110 milliliters of test compound formulation by use of a DeVilbis spray gun set at 400 psig. air pressure. This application, which lasted 30 seconds, was sufficient to wet the plants to run-off. As a control, 100-110 milliliters of a water solution containing acetone and emulsifier in the same concentrations as the test compound formulation, but containing no test compound, were also sprayed on plants infested with eggs. The sprayed plants were held at 80±5° F. and 50±5 percent relative humidity for four days, after which a microscopic examination was made of unhatched (dead) and hatched (living) eggs.

In these tests the pesticidal activity of the compounds against mites and mite eggs was rated as follows:

A=Excellent Control

B=Partial Control

C=No Control

Preliminary Herbicide Seed Germination Test

The following seeds were used in this test:

Perennial rye grass--Solium perenne

Crabgrass--Sigitaria sanguinalis

Red root pigweed--Amaranthus retroflexus

Mustard--Brassica pncia var. foliosa (Florida broadleaf)

Two seed-soil mixtures were prepared as follows:

Mixture I

196 cc. Rye grass seed

75 cc. Amaranthus

18,000 cc. Sifted, fairly dry soil

Mixture II

99 cc. Crabgrass seed

33 cc. Amaranthus

18,000 cc. Sifted, fairly dry soil

Each of the above mixtures was rolled separately in 5 gallon containers for approximately one-half hour on a ball mill to insure uniform mixing of seeds and soil. For each compound four 3-inch pots were filled with soil to within 11/2 inches of the top of the pots. To two of these pots was added 70 cc. of Mixture I. To the remaining two pots was added 70 cc. of Mixture II. The seed-soil mixture was tamped firmly, and the pots were removed to the greenhouse and watered lightly. About 2 hours after planting, 25 milliliters of the test formulation were added to each of two pots for each soil-seed mixture; i.e., one replicate of each seed mixture per concentration. An equal volume of a water solution containing acetone and an emulsifier in the same concentration as the herbicidal mixture but without the candidate herbicide was also added to each of the soil-seed mixtures. These pots are used as as check or control units. The test compounds are formulated by standard procedure of solution in acetone, addition of an emulsifier, and dilution with water. Tests were conducted on all compositions at low concentration (100 ppm.). Certain compositions were also tested at high concentration (1000 ppm). The pots were held in the greenhouse and watered lightly until results were taken. Ten to twelve days after application of chemical, injury is noted for each species by comparing treated vs. untreated pots. Ratings are made at both the high and the low concentrations (1000 ppm and 100 ppm) according to the following designations:

5=no seedlings emerged

4=few seedlings emerged and/or very severe stunting

3=moderate reduction in stand and/or moderate stunting

2=very slight reduction in stand and/or slight stunting

1=no injury; seedlings appear no different with respect to stand and/or growth than untreated controls

POST-EMERGENT HERBICIDAL TEST

Experiments were also conducted to determine the phytotoxicity of representative compositions with respect to healthy fresh plants. Solutions of the compounds were prepared as described above to provide a concentration of 2500 parts per million of the test compound. The test plants were sprayed in accordance with the procedure described above for the Mite Foliage Spray Test so as to deliver approximately 100 milliliters of test solution to the leaves of each plant tested. The sprayed plants and controls were set aside for approximately one hour to allow the solutions to dry and were then placed in the greenhouse. After ten days the plants were visually inspected to determine the extent of foliage injury. A rating of 1 indicates no perceptible injury; 5 indicates the plant was dead and ratings of 2, 3 and 4 indicate intermediate degrees of injury based upon the number and extent to which leaves were injured.

The results of these experiments are summarized and set forth in Tables I and II below.

It will be understood that the plant species employed in the above tests are merely representative of a wide variety of plant pest that can be controlled by the use of the compounds of this invention. The compounds contemplated in this invention may be applied as mite ovicides, miticides and pre-emergent herbicides according to methods known to those skilled in the art. Pesticidal compositions containing the compounds as the active toxicant will usually comprise a carrier and/or diluent, either liquid or solid.

Suitable liquid diluents or carriers include water, petroleum distillates, or other liquid carriers with or without surface active agents. Liquid concentrates may be prepared by dissolving one of these compounds with a nonphytotoxic solvent such as acetone, xylene, or nitrobenzene and dispersing the toxicants in water with the aid of suitable surface active emulsifying and dispersing agents.

The choice of dispersing and emulsifying agents and the amount employed is dictated by the nature of the composition and the ability of the agent to facilitate the dispersion of the toxicant. Generally, it is desirable to use as little of the agent as is possible, consistent with the desired dispersion of the toxicant in the spray so that rain does not re-emulsify the toxicant after it is applied to the plant and wash it off the plant. Nonionic, anionic, amphoteric or cationic dispersing an emulsifying agents may be employed, for example, the condensation products of alkylene oxides with phenol and organic acids, alkyl aryl sulfonates, complex ether alcohols, quaternary ammonium compounds, and the like.

In the preparation of wettable powder or dust or granulated compositions, the active ingredient is dispersed in and on an appropriately divided solid carrier such as clay, talc, bentonite, diatomaceous earth, fullers earth, and the like. In the formulation of the wettable powders the aforementioned dispersion agents as well as lignosulfonates can be included.

The required amount of the toxicants contemplated herein may be applied per acre treated in from 1 to 200 gallons or more of liquid carrier and/or diluent or in from about 5 to 500 pounds of inert solid carrier and/or diluent. The concentration in the liquid concentrate with usually vary from about 10 to 95 percent by weight and in the solid formulations from about 0.5 to about 90 percent by weight. Satisfactory sprays, dusts, or granules for general use contain from about 1/4 to 15 pounds of active toxicant per acre.

The pesticides contemplated herein prevent attack by insects and mites upon plants or other material to which the pesticides are applied, and they have relatively high residual toxicity. With respect to plants, they have a high margin of safety in that when used in sufficient amount to kill or repel the insects, they do not burn or injure the plant, and they resist weathering which includes wash-off caused by rain, decomposition by ultra violet light, oxidation, or hydrolysis in the presence of moisture or, at least such decomposition, oxidation, and hydrolysis as would materially decrease the desirable pesticidal characteristic of the toxicants or impart undesirable characteristics, for instance, phytotoxicity, to the toxicants. The toxicants are so chemically inert that they are compatible with substantially any other constituents of the spray schedule, and they will be used in the soil, upon the seeds, or the roots of plants without injuring either the seeds or roots of plants. They may also be used in combination with other pesticidally active compounds. When used as miticides they will normally be applied to the foliage of the plants to be treated. When used as herbicides they may be used in the soil or directly upon the seeds to be treated. The compounds of this invention may also be used in combination with other pesticidally active materials.
